- C. Remove the overloaded statement from Router-1.
- D. Remove the ISO address fromge-0/0/2 on Router-1

There are two interfaces with ISO addresses on Router-1, and they have different area IDs, 002 and 003. Only one interface on Router-1 need to have an ISO address.

Answer: B,C
Explanation:
B: RSTP and STP can co-exist. RSTP achieves its rapid converges over STP through new mechanisms. If a RSTP switch connects to an STP switch, the RSTP switch will drop down to STP convergence speeds on a per-port basis.
C: Unlike 802.1d (STP), 802.1w (RSTP) uses Hello packets between bridges to maintain link states and does not rely on the root bridge.
